I personally did not notice a difference in sound quality loss when 2 individual powered devices were connected. I am a size 8 but ordered 8. A huge disappointment in an otherwise terrific shoe. I have worn Cleo Croc sandals for years and the style and design has changed. Excellent traction even on slippery surfaces. Makes sure to get at least a whole size smaller. They fit perfectly, the color is gorgeous, and the quality is amazing. The tool was provided by Thule. You will never convince me this is an authentic Plantronics headset. I wear a womans 6.
